Matthew Romaine is a founding partner and director at a METI-authorized Tokyo VC that pools tax-advantaged capital to back Japan’s next generation of founders. He previously co-founded Gengo, scaling the human-powered AI training data platform to 22,000+ workers, raising over $25M from top VCs and exiting to Lionbridge. A dual CS and Music Theory graduate who studied at Stanford CCRMA, he blends deep technical product experience—from audio codec R&D at Sony to building platform infrastructure—with founder-level operational leadership. He now advises and invests across consumer tech, climate/sustainability, and productivity startups, serves on public company and H2 leadership roles, and mentors Techstars cohorts. Outside dealflow he’s a triathlete, ryokan owner and hands-on dad, a mix that informs his long-term, founder-first perspective.
